` DISPLAY DEVICE.

Application filed March 30,1925. Serial No. 19,406.

`ifi 'lourth important ob tion is to provide novel sign i'or such a device.

With the above and bject ot the invention for such jecto the invensh ittingmeans "other objects in view will be hereinafter apparent, the invention-consists in general o tails ot construction and parts hereinat'ter fully in the accompanying d cally claimed.

Figure 7 is the electric connecti Tn the present emb whereon is a socket 12 supporting gated lamp ard 11 is a or collar 15 13. Extending trame 14 provided which not only iront end of the socket but also rec 13. This sleeve has, at

base ot the lamp its inner end a gourna 17 which is conn mounted a disk rods 18 with a sinn lar disk 19 provi t certain novel decoinbinations of illustrated rawings and specifidrawings like charts in the of the invention vation taken `1from Figure 5 is a section similar to Figure 4,

l view, suba wiring diagram illustrating ons of the device.

odiment ot the invention there is provided a base 10. At one end ot this base there is mounted a standard 11 an elonfrom the standwith a sleeve supports the eives the l bearing whereon is ected by ded with Vcle-energized a spring 31 forces y receives current `mounted in this bracket is abar whereon 1s pivoted a pawl 26 engaging the ratchet` 23 when reciprocated'to rotate, the latter being step by stepV movement. Also at this end of the device'issupported a bracket 27 whereon is mounted a magnet 28 having a pivot armature from whichextends an arm 30 connected to the rod 25 so that each time the magnet is energized the rod is pulled in one direction and ea'ch time the magnet is the 'rod backwardly. Y Thus,l by energization oit' the magnet the rod 25 is reciprocated and the traine formed by the alternate energization and de-k disks 17 and 19 and bars 18 are interniittently rotated.

At the end ot the device carrying the magnet there is provided a block 32 whereon is mounted spring bar 33 and a second spring bar 34 ot' expandable material, these two being united at the ends remote from the block `32 to a connector block and carrying a contact 35. From a suitable source ot electric energy a wire or conductor 36 leads to the bar 33.` The bar 34 is surrounded by a heating coil 37 one end otI which is connected to the bar 33 while its other end is connected by a the source of energy. tions current Under these conchiiowing through the-coil 37 will heat bar 34 and expand the same. This will cause movement of the contact 35, which is connected to the bar 33. Supported adjacent the contact is a second contact 39 which is engaged by the contact when the bar 34 is expanded. The contact 39'is connected by a wire 40 with the magnet 28 and this magnet is in turn connected by wire 41 with the wire 38. A lamp 42 is shunted off the wirey 41 and grounded as at 43, the ground wire being indicated at 44. Under these circumstances the resistance .34 and closes the contacts 35 and 39. This short circuits the current through the magnet 28 and also through the lamp 42. Consequently the magnet 28 is energized, the frame supporting the signs is rotated and the llamp is flashed.

However, as soon as this short circultmg takesplace the coil 84 coolso and the L spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired toV include all such asproperly come Within the scope claimed. A

Having thus described the invention, What is claimed as new, is:

In a device of the kind described, a base, a standard fixed to said base, a second standard fixed to said base in spaced relation to the first standard, a frame consisting of a pair of plates and rods connecting the same,

a lamp socket carried by the second standard and having one portion thereof arranged to constitute a Journal, one plate of said frame 30 having an opening fitting said journal andV constituting a bearing for the frame, the first standard having an opening in its top and the second plate of the frame being provided with an extension constituting a journal for the frameandfitting the opening u in therst standard, a ratchet Wheel mounted on the last mentioned journal, a bracket of inverted J-shape havingl its longer leg fixedto-the base, said bracket having its upper portion overhanging the ratchet and its terminal portion depending in parallel relation tothe longer leg, a rod aligned above the ratchet and slidably mounted in the longer leg and terminal portion` of the last mentioned bracket,va pavvlpivoted to said rod and having one end depending therefrom to engageV the vratchet and the remaining end extending over the rod to limit movement of the paWl vin one direction, a second 'bracket mounted on` the base in alignment with said ratchet, a magnet ycarried byV the last mentioned bracket, an

armature pivoted below said' magnet, and an arm carried by said armature and connected to said rod whereby to move the rod upon energizaton of the magnet land thereby actuate the ratchet. Y i

n testimony whereof I affix my signature.
